Lumen tells you what the light is doing, and when it will change. Built for photographers, useful for anyone who cares about sunrise, sunset and the dark hours. Everything about the sun and moon is worked out on the watch itself, so it works with no phone and no signal, anywhere in the world. Clouds and aurora come from the internet when your phone is in range. SEVEN PAGES, SWIPE OR PRESS UP AND DOWN - Light now: the current phase, the next change with a countdown, where the sun is, and the cloud cover - Sun path: the sun's height through the day with the golden hour band, the moon's curve, and a compass strip so you can find north - Today's times: first light, blue hour, sunrise, golden hour, sunset and night, with daylight length and how many minutes you gained or lost since yesterday - Sky ahead: cloud cover and rain chance for the hours to come, plus visibility - Moon: phase, rise and set, and how long until the next full or new moon - Night sky: the hours of true darkness, the Milky Way core, moonlight, and aurora activity - Camera: suggested starting settings for the light right now MAKE IT YOURS Turn off any page you do not use, on the watch with the MENU button or in the Connect IQ app on your phone. FAR NORTH AND FAR SOUTH Midnight sun and polar night are handled properly. When the sun never rises or never sets, Lumen says so. Camera settings are a starting point, not a light meter.

Sky ahead: cloud and rain now have their own icons and columns, so the percentages no longer overlap
